What's the Key to a High IQ? It May Be More Than You Think

Stockbyte/Thinkstock(PHILADELPHIA) -- A high IQ score is a result of two factors, according to a new study by researchers at the University of Pennsylvania: high intelligence and a high motivation to take tests.

A low IQ, the study’s authors found, could result from a lack of any of the two factors.

Researchers concluded that relying on IQ scores as a measure of intelligence alone could be misleading.

Their findings were published in the Proceedings of the National Academy of Sciences.
